    摘要: A multiprotocol transport network (MPTN) gateway provides transparent interconnection of two or more SPTNs running different transport layer protocols to form an integrated heterogeneous MPTN. The MPTN gateway of the present invention has no dependencies on the particular transport protocols running on the SPTNs being interconnected as it utilizes a common transport provider (a Gateway Services Protocol Boundary (GSPB)) between the SPTN transport protocols and the gateway components. The MPTN gateway supports connections between end systems across multiple intermediate networks. The MPTN gateway provides automatic routing based on dynamic participation in the routing protocols of the interconnected SPTNs so that any number of gateways may be interconnected and in any topology desired. As the MPTN gateway has a general architecture and acquires routing information automatically, it supports not only other MPTN nodes and gateways but also non-MPTN nodes and gateways.

    摘要: A mechanism is provided for secure PIN management of a user trusted device. A user trusted device detects a memory card coupled to the user trusted device. The user trusted device receives user input of an external PIN (ext_PIN). The user trusted device identifies a key (K) associated with the external PIN, wherein the key is stored in the persistent memory. The user trusted device computes a card PIN (card_PIN) using a function (f) and the key as stored on the persistent memory, wherein the card PIN is computed using the following equation: card_PIN=f(K, ext_PIN). The user trusted device unlocks the memory card using the card PIN, thereby forming an unlocked memory card.

    摘要: A system for interconnecting widely separated local area networks (LANs) by means of a wide area network (WAN) utilizes network level facilities to establish a connection through the wide area network and to create connection table entries at the WAN access point which allow subsequent data frames to be transmitted through the wide area network without such network level operations. More particularly, the various LANs are combined into search groups, represented by address prefixes, to which LAN-initiated connection requests can be broadcast and which can respond so as to establish the data path connections. This system has the connection flexibility of a prior art router and, at the same time, the low overhead of a prior art bridge.

    摘要: A security device (6) is provided for facilitating management of secret data items such as cryptographic keys which are used by a remote server (2) to authenticate operations of the server (2). The device (6) has a user interface (13), control logic (16) and a computer interface (11) for connecting the device (6) to a local user computer (5) for communication with the remote server (2) via a data communications network (3). The control logic is adapted to establish via the user computer (5) a mutually-authenticated connection for encrypted end-to-end communications between the device (6) and server (2). In a backup operation, the secret data items are received from the server (2) via this connection. The control logic interacts with the user via the user interface (13) to obtain user authorization to backup secret data items and, in response, stores the secret data items in memory (10). To restore secret data items to the server, the control logic interacts with the user via the user interface (13) to obtain user authorization to restore secret data items and, in response, sends the secret data items to the server (2) via said connection.
